This clutch pump repair kit contains the seals, gaskets, and wear components needed to restore the clutch pump to its original operating condition. The kit sits between the pump housing and the internal piston assembly; its components seal the high-pressure chamber that supplies the clutch pack. A leaking or worn pump causes a gradual loss of clutch engagement pressure, leading to slipping or incomplete disengagement. The manufacturer machines each component to match the original pump's bore and groove dimensions, so the piston slides freely without bypassing fluid. On reinstall, clean the housing bore and lubricate the new seals with hydraulic fluid before assembly.
